#Black magic battery requirement series
I can either use the D-tap output which combines the voltage of the two batteries in a series circuit for the 12V input of the camera (or other applications like LEDs). So now I can use my AA batteries and can charge or replace them individually. And in the pictures you can see two 6xAA battery packs with NFP output. I can use Sony NFP batteries with this and I have two adapter plates so Canon LP-E8 will work as well. I've managed to tinker me some solution as I intended to. I like the smaller form factor and reduced weight on Dmitry’s battery pack.įor Dmitry’s better pack, See. For longer runs, I use a Anton Bauer 14.4 VDC Camera Battery on a Gold Mount plate, which runs for 6-10 hrs. It gives around a 2-3 hour run time, which works for me. I use Dmitry’s Micro camera battery pack, which uses 4 18650 batteries and outputs around 14-16 VDC. So to answer your question as to which voltage is more efficient, the larger external 20-12 VDC input is only going to require down conversion, which is more more efficient, less loss, than up-conversion. The internal battery is connected to the DC-DC board at s different tap, so it might have some if it’s voltage stepped up. The new Pocket 4K has a much higher 22watt average pier requirement, and it is the power load, along with the required voltage that drives an external power source. I have tried running the original Pocket camera with a large 7.2 VDC battery (which was around 9.x VDC fully charged, and it would power up the small Pocket camera if I had an internal battery in it (not a BMD recommended practice when using a 12-VDC upscaling source) the original Pocket camera was combining the two batteries together at the DC-DC power supply, but this was not very good, and only Extended the run time by around 50 percent, not 2X as one would think. The advantages of using a normal 14.5 VDC camera battery is, the higher voltage and MA provide more power, and 14 VDC an given amperage will provide the required 12 VDC level longer than a battery that only outputs 12 VDC at the same amperage, See Ohm’s law to see how this works. Most batteries do not output a constant voltage output anyway, unless connected to a regulated power cable (another conversion process), so get get a battery or other power source with the correct voltage level. Short answer not really, any voltage level used will require some type of conversion.
